3. INTRODUCTION Heat storing sand batteries are a type of renewable energy storage technology that utilizes the heat capacity of sand to store and release thermal energy. These batteries work by heating a volume of sand to a high temperature using excess renewable energy, such as from solar or wind power 2/15/2023 3

4. Working Heat-storing sand batteries store thermal energy in sand, which can then be used to generate electricity. The batteries consist of two tanks of sand, one at a high temperature and one at a low temperature, connected by pipes containing a heat transfer fluid. When the battery is charged, the heat transfer fluid is pumped through the pipes from the hot sand tank to the cold sand tank, transferring thermal energy from the hot sand to the cold sand. The stored thermal energy can be used to generate electricity by transferring the heat to a heat engine, which in turn drives a generator to produce electricity. 2/15/2023 4
